What is the final function of fixing?

Explanation:
Fixing makes the image permanent by hardening the gelatin in the emulsion. This hardening stabilizes the image so it stays intact during washing and handling, and it helps protect the image from scratches and damage over time. While fixing does remove unexposed silver halide crystals, and that clearing action is necessary, the lasting, defining effect is the hardening of the emulsion which secures the finished image. Developing creates the image, so that step is done earlier. Washing away unexposed crystals occurs during fixation but is not the final stabilizing action. Drying happens after washing and fixing.
